How the index works
- Constituents: US-listed companies (ADRs included) whose AI-infrastructure revenue is 50% or more of the total (pure play) or 20–50% (significant, held at half weight), in seven segments. In power, electrical and cooling equipment, and construction, a company that discloses no figure but names a current data-centre business in its annual report is held at half weight.
- Eligibility at each reconstitution: free-float market cap of $1bn or more and three-month average daily traded value of $10m or more ($0.75bn and $7.5m for existing constituents), and three months of trading. A new listing with a free-float market cap of $5bn or more joins after ten trading days.
- Weighting: modified free-float market cap. No name above 8%, or above 12 times its uncapped weight; names above 4.5% at most 40% combined; each segment between 7.5% and 30%, unless its names cannot reach 7.5% within that ceiling. The capping is iterative, so every limit holds at once at each rebalance.
- Calendar: rebalanced after the close on the third Friday of March, June, September and December, with full reconstitution in June and December. Selection ten trading days before, announcement five trading days before.
- Calculation: Laspeyres divisor method on licensed end-of-day closes. The divisor is adjusted for every corporate action so the level is unaffected. The net total return version reinvests dividends net of 30% withholding for non-US issuers.
- Base: 30 December 2022 = 1,000. Every value before the launch date is a hypothetical back-test with today's constituent universe.

Compute Terminal, methodology version 1.0. Price data: Intrinio. Share counts and public float from SEC EDGAR filings. Values before 11 Nov 2026 are a hypothetical back-test: the index did not exist then, the constituents are drawn from today's universe, and past performance, real or simulated, says nothing reliable about the future. Index changes are announced five trading days before they take effect; restatements and methodology changes are logged. See independence and conflicts and corrections. Not investment advice.
